Setting Up MySQL

Hi Everyone!

I know I haven't been posting much these past few months, I was busy with many other things and I decided to take a breather with blogging. However, things have cleared out of my way now, and I will start again with posts.

Installing:

For Linux users, type the following into your command line:

shell>sudo apt-get install mysql-server
shell>sudo apt-get install mysql-client

For Mac and Windows users, you have to download the installer here. Make sure you check 32 or 64 bit! Follow the steps that the install gives, and you should be fine!

Using MySQL:
To start up MySQL:  type the following commands in the terminal:
shell>mysql -u root -p
It would ask you for your password, since you need to be the root user. The installation should ask for you to set a password for MySQL, which is optional. If you do not wish to set a password, you can just click enter when it prompts you to type in a password.

If you did not set a password for MySQL, you can disregard the "-p" part. You can also just type it and click enter when it asks for a password. If you get in, you should see something like this:
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 1
Server version: 5.6.27 MySQL Community Server (GPL)

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
mysql>

For Windows users, here's the way to start it up. I haven't tried this but I hope it helps.

To create a database: type the following in the MySQL command line:

mysql>create database database_name;

Notice here that you need a semicolon to show that you're done talking. We'll see later how that semicolon can be changed to something else.

To go into a database: type the following in the MySQL command line:

mysql>use database_name;

type in "mysql --help" in you're computer terminal to see many, many other commands.

Changing MySQL Password:

In order to change your MySQL password you will need to log onto MySQL first. After that you type the following:

mysql>grant all privileges on *.* to root@localhost identified by "new_password";

Here, the new_password should be in the quotes.

Changing the Terminator Symbol:

The semicolon at the end of each command is usually called the terminator, which tells MySQL that you're done with a statement. But what if you wanted to paste a big chunk of commands? Or paste in a function? You can change the terminator symbol before you paste code, and change it back to semicolon afterwards. Here's how to change it:

mysql>DELIMITER YOUR_TERMINATOR

example: mysql>DELIMITER done

In this example, assuming you don't have the word "done" in your code, will end your set of commands when it find the word "done." To change it back to semicolon you would do the same except with a ";"

That's it! Pretty Simple huh? If you have any problems look it up, many people may have the same problem. You can also feel free to post a comment here, and please do so if my post here helped you! I really appreciate knowing that I have helped! 'Til next time.

*It also seems that the spacing of this post is really odd, I'm trying to fix it but I haven't figured out the cause so far.
